- WHEELrTRUCK FOR DISK HARROWS.

Specification of Letters Patent. Patented Nov. 10, 1908.

Application fi1e d hpril.6, 1 907. SerialNo. 366,697.

To all tvhom it may concern:-

Be it known that I, FRANK K. IiA'rHnoP,a

' citizen of the United'States, residing in Dayton, county of Montgomery, and State of Ohio, have invented certain new and useful Improvements in WheeLTrucks for .Disk

' I-Iarrows andthe Like, of which, the following 1s a full, clear, and exact description,

re e

rence being had to the accompanying drawings, forming part of this-specification. The purpose of my invention is to, provide ,wheels or trucks to support the forward end on the stub pole of a disk harro'w, or like im-' plement, in'order to avoid the objections ofside draft, neck weight, and the jerking n1o-.

tion of the .pole in rough uneven ground, re-' novel construction and arrangement of parts to be hereinafter and claimed.

In the drawings I have not thought it necessary to illustrate any construction of disk harrow, or other implement, as the invention relates only to the support on the particularly pointed out front end of the stub pole of the implement.

In the draWings,Figure 1 is a perspective view of my improved truck. Fig. 2 is a central vertical cross section of same, and Fig. 3 is a similar longitudinal section.

- 1 is a sleeve formed with the bottom flange 2, around its front portion, and with the plate 3 extending rearwardly. -This plate 3 is securely bolted to the front end of the stubpole 4: of theimplement.

Journaled in the sleeve 1, so as to turn freely therein, is the vertical hollow pipe 5. Upon the uper end of this pipe are securely bolted by the bolts 6'-6 the connecting; irons 7, to which the draft pole 8 is bolted. When it is desired to provide an offset pole for three draft animals, the connecting iron 7 is extended out to one side as illustrated in Fig. 2, by dotted lines.

When it is desired to'use the implement without a pole or tongue, these connecting irons and the pole are unbolted and removed from the hollow pipe.

pivoted or journaled in the lower ends of the arms of this yoke are the ends of the right angular extensions 11 from the middle poi tion of the tubular box or casing 12, which carries the axle 13, upon which are, mounted the truck wheels 14l.14. These'wheels are preferably provided'with awide tire,- metal spokes, and dust .proof journal boxes, the wheels being held on the axle by the cotter pins 15.

Between the sleeve 1 and the yoke 9 on the pipe 5 is the draft-arm clevis casting 16, which'is secured to the pipe by bolts 17.

v This clevis casting carries the upwardly extending arm 18, provided with a groove to,

engage the flange 2 on the sleeve 1, and. a series of holes 19 are provided through the. pipe 5, so that this clevis casting can be raised or lowered which will raise or lower the sleeve 1, and thus raise or lower the stub pole of the implement. The forwardly extending end of the cleviscasting 16 is provided with a series'of holes 20 for attaching tion that the carrying wheels can tip in the yoke 10 to conform to any unevenness 'in the ground, and that the height of the carrying wheels is such that they can always turn under the stub pole l of the implement, so that a square turn at right angles may very readily be made.

By providing a yoke which carries journal bearingsfor the axle of the truck, which are transverse to the axis of the truck wheels, or disposed in a line with the travel of the im' plement, I not only provide a rigid substantial construction, but a'm able to secure the tongue of the implement, when a tongue is desired, on a line with or above the stub pole.

Heretofore in truck constructions, in which provision is made for both vertical 'and horizontal pivotal movement, it has been lifting one of the wheels from the ground;

With my construction I am able to secure the tongue on a line with or above the stub pole,

- because I provide for the truck, by means of my yoke, a wide transverse bearing in a line with the travel ofthe implement, which effectually prevents the tipping.

Havin thus described my lnventio what 1. a vheel truck for a gricultural'iinple; inents, he .con'iblnatlon' with ant-implement tudinally -adjustable and-"means ffo ng me on sa d'pole to rotate on ke' secured to the lower-en \lliaving a fstub pole, of a "vertical shaft lo n 1- (t-nrn al bearings on s the inipl 1119 and approximately atxthe axis o the els'of thet-ruck and aecleris caste in}; for '-holdi1 1g the hitching" elevis, adjust: mounted on sa d-shaft, Wit-h connection between sald'clerls casting and the stub pole,
